i want to do the following. I am having a google map that displays my position. I have created separately a compass. Now what I want is to combine them and put the compass on top of my map. I do not know where to start for it, and how I skould implement it since data of te compass are also being updated every second I move?

If you have any tutorials please give me link cause I have not been able to find any.

In my previous app I have used a class extending Overlay but this was for only putting a pin or something like this.
